The control group was treated with methylphenidate hydrochloride tablets and tiapride hydrochloride, and the observation group was treated with Jingling oral liquid on the basis of the control group. Both groups were treated continuously for 16 weeks. The clinical efficacy and number of seizures of the two groups were compared, the clinical symptoms of the two groups were assessed by the Conner Parent Symptom Questionnaire (PSQ) and the Swanson Nolan and Pelham Version Ⅳ(SNAP-Ⅳ), and the intelligence level of the two groups was assessed by the Wechsler Intelligence Scale. The serum levels of DAT, IL-6, 8-iso-PGF-(2α), neurotrophic factors before and after treatment and the occurrence of adverse reactions were compared between the two groups.Results:After treatment, the effective rate in the observation group was higher than that in the control group: 93.33% (56/60) vs. 80.00% (48/60), there was statistical difference ( χ2 = 4.62, P<0.05). After treatment, the number of seizures in the observation group was less than that in the control group at 3, 4 to 6, 7 to 12 months: (10.78 ± 1.45)times vs.(14.18 ± 1.56) times, (4.86 ± 0.53) times vs.(8.63 ± 0.89) times, (2.64 ± 0.32) times vs. (4.11 ± 0.45) times, there were statistical differences ( P<0.05). After treatment, the scores of PSQ and SNAP-Ⅳ in the observation group were lower than those in the control group: (13.67 ± 1.48)scores vs. (15.18 ± 1.59) scores, (22.12 ± 2.35) scores vs. (25.37 ± 2.68)scores; while the scores of Wechsler intelligence scale was higher than that in the control group: (93.65 ± 9.77)scores vs.(89.42 ± 8.89) scores, there were statistical differences ( P<0.05). After treatment, the serum levels of DAT, IL-6 and 8-iso-PGF-(2α) in the observation group were lower than those in the control group: (0.46 ± 0.05) μg/L vs. (0.52 ± 0.06) μg/L, (8.26 ± 0.89) ng/L vs. (8.74 ± 0.92) ng/L, (60.38 ± 6.46) ng/L vs.(79.25 ± 8.14) ng/L, there were statistical differences ( P<0.05). After treatment, the serum levels of S100βprotein, brain-derived nerve growth factor and prolactin in the observation group were higher than those in the control group: (41.55 ± 4.28) ng/L vs. (37.26 ± 3.87) ng/L, (498.33 ± 54.26) ng/L vs.(442.15 ± 45.78) ng/L, (10.18 ± 1.14) μg/L vs. (9.69 ± 0.97) μg/L, there were statistical differences ( P<0.05).There was no significant difference in gelatinous-derived nerve growth factor level between the two groups after treatment ( P>0.05).

Conclusions:Jingling oral liquid combined with methylphenidate hydrochloride and thiopride hydrochloride in the treatment of ADHD co-induced by epilepsy has good efficacy, and can significantly improve their clinical symptoms, regulate the levels of serum DAT, IL-6, 8-iso-PGF-(2α). It is safe and reliable.

Extracellular vesicles(EVs)are small vesicles secreted by cells,widely present in various body fluids,and they play important biological roles.In recent years,EVs have garnered significant attention as novel diagnostic and thera-peutic tools in multiple ocular diseases.Glaucoma,as a common cause of irreversible blindness,is primarily caused by optic nerve damage associated with pathologically elevated intraocular pressure.Emerging evidence indicates that EVs hold considerable therapeutic potential in glaucoma management,particularly in modulating aqueous humor circulation and pro-viding retinal neuroprotection.This review summarizes the latest research progress on EVs in the treatment of glaucoma.

This study was aimed at establishing a method of ultra-fast quantitative PCR for Brucella detection.We used an exogenous recombinant plasmid as the internal reference and targeted the T4SS secretion system,an important Brucella viru-lence factor,to design specific primers and probes.The sensitivity,specificity,and repeatability of this method were evaluated,and a standard curve was constructed.The coincidence rate of detection findings with this method versus quantitative PCR was determined.This method markedly decreased the detection time to only 10 minutes.The standard curve demonstrated a good linear relationship(Y=-3.410 7x+38.357,R2=0.998 5)with a low minimum detection limit of 10 copies/μL.The method exhibited good specificity and did not specifically amplify several common clinical bacteria other than Brucella.The de-tection of three concentrations of positive plasmids yielded coefficients of variation(CVs)of 0.20％to 0.91％,thus demonstra-ting the method's excellent repeatability.Furthermore,140 clinical samples were analyzed concurrently with the fluorescence PCR method,which yielded a 100％compliance rate and consistent results.Our findings indicated that the Brucella ultra-fast quantitative PCR was ultrafast;had high sensitivity,high specificity,and good specificity;and can be used for the clinical de-tection of Brucella and emergency investigation of epidemics.Therefore,this method is valuable for the early diagnosis of Bru-cella.

Drug resistance refers to the reduced or lost sensitivity of microorganisms to key drugs used in clinical (routine) treatment. Antimicrobial resistance poses a significant threat to global public health and safety. The misuse and abuse of antibacterial drugs not only causes inefficient treatment of bacterial infectious diseases, but also exacerbates the evolution of bacterial antimicrobial resistance and the spread of antimicrobial-resistant bacteria. As one of the cutting-edge scientific techniques, microfluidic chip technology has shown extensive application potentials in various fields. In the rapid detection of drug-resistant bacteria, microfluidic chip technology has the advantages of fast speed, high degree of automation, and the ability to perform multiple detections. This article focuses on bacterial antimicrobial resistance, and briefly introduces the principle of microfluidic chips, systematically outlines the application of microfluidic technology in antimicrobial resistance detection, and provides a theoretical reference for the diagnosis of clinical bacterial infectious diseases.

Objective:To evaluate the short-term efficacy of our modified anterior pelvic ring internal fixator(INFIX) in the treatment of anterior pelvic ring injuries.Methods:A retrospective study was conducted to analyze the clinical data from the 16 patients with pelvic anterior ring injury who had been treated with our modified INFIX at Department of Orthopaedics, The First Hospital Affiliated to Bengbu Medical University from June 2020 to June 2023. There were 9 males and 7 females with an age of (49.1±14.3) years. According to the AO/OTA classification, 10 cases were of type B2 and 6 cases of type C1. Their time from injury to surgery was (7.6±2.9) days. Fixation with our modified INFIX was as follows: Three pedicle screws were inserted into the anterior inferior iliac spine on one side and into the pubic symphysis on both sides. Next, a subcutaneous tunnel was created from the anterior inferior iliac spine incision toward the pubic symphysis, and connecting rods were inserted for fixation. The surgical incision length, intraoperative blood loss, surgical time, postoperative fracture reduction quality, fracture healing time, incidence of complications during follow-up, and pelvic functional recovery at the last follow-up were recorded in this cohort.Results:In this cohort, surgical incision length was (5.8±0.4) cm, intraoperative blood loss (75.4±11.9) mL, and surgical time (66.1±8.9) min. By the end of one week after surgery, the quality of fracture reduction was evaluated according to the Matta scoring criteria as excellent in 11 cases and as good in 5 cases. All patients were followed up for (17.4±3.1) months after surgery. The fractures got united in all the 16 patients after (11.2±1.2) weeks. At the last follow-up, the pelvic function recovery was evaluated according to the Majeed scoring system as excellent in 13 cases and as good in 3 cases, yielding a Majeed score of (90.1±4.2) points. During the follow-up period, no patient developed complications such as nerve injury, wound infection, or loosening, breakage or withdrawal of internal fixation devices.Conclusion:In the treatment of anterior pelvic ring injuries, our modified INFIX has the advantages of few complications, simple operation and minimal invasion, leading to good short-term efficacy.

Glaucoma,characterized by optic nerve damage and progressive damage to retinal ganglion cells(RGCs),is the leading cause of irreversible blindness.However,the specific mechanism of RGC damage has not been fully elucida-ted.In recent years,there is increasing evidence that microglia,especially disease-associated microglia(DAM),may play an important role in glaucomatous ganglion cell injury.In this paper,we reviewed the role and mechanism of DAM in RGC damage in glaucoma,aiming to provide new insights for further research on the mechanism of RGC damage and subsequent protection of RGCs.
